1. Is there a way to tell from a piece of code that you are being called from cinit ? eg. in C++ when a constructor causes some code to run, and that calls some function, and then I get called, is there anything I can check to see that I'm currently in cinit, not main?
(obviously a very evil thing I could do is run a stack trace and see what's at the top of the stack). I can't find anything in C that I can check, because the C stdlib is initialized before me, so to my cinit code it looks just like I'm in the app run.
The reason I want this is mainly for asserting & validation - I want to make sure that my own cinit code isn't calling certain things (such as memory allocation) so I want to put in checks like ASSERT( ! in_cinit() );
2. Is there a way to disallow cinit code in certain modules? For example, having cinit stuff in any library is very unsafe because you have to be wary that your OBJ could get dropped from the link and the cinit stuff will not be run, plus you have order of run issues, it's something I can handle fine in my own projects, but not something I want to force on clients. So I want to make sure that my actual deliverable libraries have no cinit stuff - but I do want cinit stuff in my test apps, so I don't want to just break it entirely. I'd really like a compiler error so I know I did a booboo right when I write it.
